A compact rolling line adjustment device

Abstract

The invention discloses a compact type rolling line adjusting device. A framework is fixed between a first arch board and a second arch board; the lower part of the framework is provided with a coarse tuning driving mechanism, a power output end of the coarse tuning driving mechanism is fixedly connected with a connecting beam, and a first step board is fixed at the end part of the connecting beam; one end of a fine tuning driving mechanism is fixed on the first arch board, and the power output end of the fine tuning driving mechanism is respectively connected with one end of each of a first inclined block and a second inclined block; the upper surface of the first inclined block is meshed with a first inclined block mechanism, and the first inclined block mechanism is fixed on the second arch board; the first inclined block is in gliding fit with the connecting beam and / or the inclined block mechanism; a second step board is fixed at the other end part of the connecting beam, and the upper surface of the second inclined block is meshed with a second inclined block mechanism, and the second inclined block mechanism is fixed on the first arch block; the second inclined block is in gliding fit with the connecting beam and / or the second inclined block mechanism. The compact type rolling line adjusting device is featured by compact structure and good rigidity.

Description

Technical field [0001] The invention relates to the technical field of leveling machines, in particular to a compact rolling line adjustment device on a leveling machine. Background technique [0002] The leveler is the key equipment of the exit section of the continuous retreat unit. The commonly used four-roll and six-roll levelers are similar in structure to other rolling mills. The rolling line adjustment device is an important auxiliary equipment of the leveler. Its purpose is to ensure that the rolling line elevation is constant after the roll is ground. It is usually installed on the upper or lower side of the archway. [0003] At present, the line adjustment device installed above the rolling mill usually adopts the form of a stepped plate and a diagonal block compound adjustment device. The structure mainly includes a frame, two hydraulic cylinders, connecting forks, a stepped plate, a slide rail, a diagonal block, etc. Part of the composition, the fixed frame part is ins...

Problems solved by technology

The combination of the two can realize the constant stepless adjustment of the rolling line between the maximum roll diameter and the minimum roll diameter. At present, the frame of this rolling line adjustment device is fixed on the outside of the archway. Due to the cantilever installation, the deflection is large and the structural rigidity is not good. However, for the 6-high skin pass machine, the amount of grinding rolls is smaller than that of continuous rolling mills and reversing rolling mills. If this mechanism is also used, the size of the device will be large and the economy will not be strong. Therefore, we have developed a compact rolling mill. line adjustment device
